Skitag IMU device position

Skitag IMU device pairing, battery and start/stop recording


Turn your App on. Navigate to the Record screen. Press the Skitag IMU device button twice until the led blinks for a second (red).

iOS: The device is paired if the Skitag IMU device label changes from Search to IMU.

Android: You must first press the button SCAN IMU to start scanning for a BLE device. The Skitag IMU device is paired if you see the Skitag IMU indicator value changing while you are moving the device.


Every time you turn the Skitag IMU device ON you'll see its battery level. This information is approximate because cell coin (CR2032) battery charge status is not accurate and it may be influenced by extreme below zero temperatures. We recommend to change the battery when it’s below 15%.

Extreme below zero temperatures may reduce the battery life. Our trainers reports that the CR2032 battery may lasts functioning in good conditions one weekend.

Skitag IMU device movements troubleshooting

Skitag IMU device movements is not sending data, i.e. stopwatch is not counting

Some users reports that Skitag IMU device stops recording, i.e. the tilt value is not changing. This may be caused by two possible issues:

The Skitag IMU device run out of battery

First, check the battery charge remaining on the Skitag IMU device movements. Reset the Skitag IMU device movements communication: 1. Stop recording or make sure it's not recording; 2. Navigate back to main menu. 3. Go to Record screen; 4. Pair again the Skitag IMU device. The App will show you the updated battery level.

If it’s too low, i.e. it's closed to zero, or if it’s labeled change battery, please remove and change the battery. If the battery level is fine, there might be some issues related to the sensor functioning under extreme below zero temperatures.

The Skitag IMU device is under extreme below zero temperatures

You may need to warm up the Skitag IMU device: Go to a warmer place. Wait for a few minutes, turn it back on and wait a few minutes before exposing it back to extreme below zero temperatures.

To avoid this issue, we recommend our trainers to turn the Skitag IMU device on and pair to the App at the moment they put their ski on. This will allow the Skitag IMU device to warm up before being exposed to extreme below zero temperatures commonly registered at the highest ski slopes.

Whatch your Skitag data

Press the Downhills button, then select the file (sorted by date and hour) you would like to watch.

Android: you'll be asked if you want to Delete or Watch the content of the file. Choose WATCH to see your Skitag data or choose DELETE if you want to permanently delete your Downhill data.

iOS: To delete your Downhill data you must swipe to the left the downhill row.

Share your Skitag data

iOS: Go to Skitag Preferences screen. Then go to Share skitag data and choose the Skitag data file you want to share with Skitag/Situalab.

Android:Go to settings menu. Choose Share Skitag data and choose the file you want to share with Skitag/Situalab.

Skitag data files troubleshooting

You don’t see your last Skitag file

Skitag App did not recorded any data. That means that your Skitag App has no acces to your GPS location.

You see your last Downhill GPS information (chrono, distance, elevation and speed) but your Skitag IMU device information is empty (ski style, ski balance and carving).

You don't have the Skitag IMU device or there is not enough ski data to populate the charts, i.e. the downhill is too short or your turns and ski time is too sparse.
